SIMULATION RESULTS OF SPECKLE SUPPRESSION IN RADAR WITH SYNTHETIC APERTURE by R. N. Akinshin, V. L. Rumyantzev, A. V. Peteshov

“…The disadvantage of (RLI) radar images obtained with a single-channel radar station is the presence of speckle that leads to intensity flashes increasing the number of false alarms when detecting point targets. Therefore, the detection and target distinguishing by their reflective capability (using the energy characteristics of the signal) is not effective enough. …”

Theory and simulations of few-photon Fock state pulses strongly interacting with a single qubit in a waveguide: Exact population dynamics and time-dependent spectra by Sofia Arranz Regidor, Andreas Knorr, Stephen Hughes

“…We present a detailed quantum theory and simulations of few-photon Fock state pulses interacting with a two-level system (TLS) in an open waveguide-QED system. For a rectangular pulse shape, we present an exact temporal scattering theory to derive analytical expressions for the TLS population, using one-photon and two-photon pulses, for both chiral and symmetric emitters. …”

Resolution improvement filter for sonar returns by A. DYKA

“…The concern of this paper is the Single Pulse Resolution Filter – SPRF, which is capable of resolving near-rectangular overlapping pulses. The reason for assuming such pulses is that despite the attractive properties of matched filter pulse compression most operational sonar systems continue to use a finite-length rectangular pulse of constant frequency. …”
